For the 2,000 revelers who attended a pool party on Saturday at the MGM Grand in Las Vegas, it was more than just a chance to escape the 115-degree heat with drinks and dancing. Turns out this particular shindig had an added bonus: the opportunity to hurl insults at host Jon Gosselin.

With eight mouths to feed and a 22-year-old girlfriend to keep in the reality show-provided lifestyle to which she's likely become accustomed, Gosselin has seemingly found gainful employment as a human punching bag.

People magazine reports that as Jon walked the red carpet on the way into the bash, one bikini-sporting partygoer climbed on a railing and hollered "Team Kate!"

In addition to a screamed suggestion to "Go sleep with that 18-year-old," an apparent reference to his youthful squeeze, Hailey Glassman, Radar Online reports some of the guys in the crowd razzed Gosselin about his bald spot; questioned him about the price of hair plugs; teased him about his non-strapping pecs; and mocked his clothes, even though he wasn't wearing his usual execrable Ed Hardy-wear.

If Gosselin was bothered, he didn't let on. With his mother and four friends in tow (Hailey, however, was a no-show), he held court in a cabana, reportedly sipping champagne, smoking cancer sticks and chatting up the packs of seemingly low standard- and low self-esteem-having string-bikinied women who were drawn to his camera-surrounded vicinity, several of whom offered up their numbers to the receptive dad.

"The kids all went swimming," says a spy. "They were splashing around in the pool and having a really good time."

At the end of the day, Gosselin, who graced the cover of last week's People magazine ("Sometimes I feel it's a 15-year-old I'm getting divorced from"), shared a rumor-quashing hug with Mrs. Neild. Score one for Team Kate.
